The current model we’ve selected is First Alert SA303 Ionization Smoke Alarm with Long-Life Lithium Battery.

Chief Benson says: "Smoke detector sensors wear out over time. If your smoke detector is over 7 years old, it may not be working."

Boulder County regulations instruct homeowners and landlords to install smoke detectors in each sleeping room AND in the immediate vicinity of bedrooms (i.e. hallways), plus one on each additional level of the house. It’s also a good idea to have one in your garage.
